CVE-2026-20793: Denial of Service in Intel(R) QAT software drivers for Windows
Unchecked return value for some Intel(R) QAT software drivers for Windows before version 1.13 within Ring 3: User Applications may allow a denial of service. Unprivileged software adversary with an authenticated user combined with a low complexity attack may enable denial of service. This result may potentially occur via local access when attack requirements are not present without special internal knowledge and requires no user interaction. The potential vulnerability may impact the confidentiality (none), integrity (none) and availability (low) of the vulnerable system, resulting in subsequent system confidentiality (none), integrity (none) and availability (none) impacts.
AI Analysis
Technical Summary
This vulnerability in Intel(R) QAT software drivers for Windows prior to version 1.13 involves unchecked return values within user-mode components. An unprivileged attacker with authenticated local access can exploit this flaw with low complexity to cause a denial of service condition. The issue affects availability only, with no impact on confidentiality or integrity. The CVSS 4.0 base score is 4.8, reflecting a medium severity level. No official remediation or patch information is currently available.
Potential Impact
The vulnerability can cause a denial of service on affected systems running Intel(R) QAT software drivers for Windows before version 1.13. It does not affect confidentiality or integrity. The impact is limited to availability degradation, potentially disrupting normal operations of the driver or dependent applications.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, restrict local authenticated access to trusted users only to reduce risk. Monitor Intel's advisories for updates regarding patches or mitigations.
